2 " = 1 16/16

2(3/16) = 6/16

1 16/16 - 6/16 = 1 10/16 = 1 5/8 "

What part don't you understand?

Answer 3

OK. Let's start with a picture of a pipe showing it's inside and outside diameter.

Do you understand that drawing?

Answer 4

Well imagine the pipe, the diameter of the pipe is 2 inches.Those 2 inched are comprised of the empty part of the pipe and its thickness, which happens to be 3/16's of an inch thick.

Now, a pipe has both a bottom and top thickness if you imagine the diameter to be vertical right? So the total thickness of the pipes edges sums to (3/16)+(3/16) which is 3/8 inches. We've now effectively lost 3/8 inches of our actual diameter of the inside to this outside thickness.

This means that the diameter of the inside should be approximately 2 inches, which is 32/16, minus the part lost to thickness which is 3/8 and you should end up with an equation that looks like this.

32/16 - 3/8 =
32/16 - 6/16 =
26/16 = 1 inch and 10/16 of an inch which is basically (1 + 5/8)''
